1908.v No claims-are madeto this engine in the present application as the same constitutes' the subject-matter. of the application aborc referred to. For the purposes of this case, it `isrhelie'red-to be sufficient to state that 'said engine consists of two or more stationary eccentriopiston members 8, 011 which is jurl'ialed a rotary cylinder member v9. This engine isprovidcd with a. cooling sys'- tem, which includes channels Vand 11 vA`formed in both the piston' and cylinder members. The cooling system in itself 4is not claimed in ths application, as it constitutes th'e subjectmatter of another (zo-pending application, Serial No. 457,350, tiled October 12, 1908. The inlet to thecoolingsystcm is vthrough one of the huhs'12 offthc engine,

and the loutlet .is preferably through Athe same hub, though this precise arrangement is. immaterial. A supply'pipc 1 3 for the cooling inedium isconnected- 'toLthc inlet' Ychannel '10,and connected to said supply pipe', is a water conductingpipe 14 leading from a suitable source (it-supply andrhaving a valve 16 therein'. A liquid fuel-lcon# 'tnctin'g pipc'l'? is also coime'ct'ed-to the supply pipe 113, and has a controlling valve 18 therein.4v It will thus. be seenA that Yeithen water or' liquid yfuel ea'n be introduced into the, cooling system df the engine.-

Leading from the hub 12 of' the'eng'ine' is an exhaust pipe 1$) for the products of combustion, 4and this pipe isjdivided -into li|:1m.lies2() and 21;- The. branch V20 the -toi-mot a. coil located within a heater, casing '22,- while thebranch 21- is disposed extcriorly of said casing. The two branches are connected to a'valrefeasingnfl, from which leads an exhaustjpipe- 24,-the`pipesv 19 and-24 thus constituting sepanlte'sec-Y tions Vof the exhaust pipe, 4which aie connected by the two branches 20 end ll'.v 1A dist'fl'iarge Vnipple 25- Vis preferably fniounted on the'.cylindermember and communicates ioa with the outlet .'channel =10 of the cooling" I system.` This nipple'd'elivers intoa'n an Y n ulan trough Qt'vsurrounding the hub 12;' 'Ai pipe 27 `tor conducting the fuel communi-: cat es with said outlet ehannel. 10 oflthe` cooling` system. and isprefeiahl'y provided with-a controlling valve 28. -This fuel coni,

This i crank arm may constitute' means-for manually actuating the valve, but 1n the pre-4 ferred fori'n .of construction, automatic meansareiemployed for this purpose. A device responsive .tot the va or 'pressure in comprising a ehambere lbody v37 mounted 'on the casing .22 and communicating with :the interior-'ofl contains ie'vaporizedoil or gas constitut' ing the fuel supply .foi-operating :the engine. A flexible diaphragm' '38 closes 4the upper` end of the body-and is conheeted'to a" bell crank .lever 39, one arm 4 of whiehcis -ful'- erumed,'asshwn at 4l'on a supporting 4 3,`to which is connected a link 44, said linkbracket 42. This arm 40 has an extension bengfalso attached-to the crank arm' 36'. The. long :117111,39 of the bell crank lever is `located labove the bracket arm 42 and its free end ,eperates 4in a suitable u )standing guide 45. spring`46, adjust'a le along the bracket 42, is. engaged with andadjust fable along the arm 39- of the lever so that the amount' -of pressure against the dia'-l pliragmBS necessary to voperate-the 'arm 39 can be varied, as'desire'd.- As the diaphragm responds to. 'varations'in the vaporpressure within 'the casing`22, the valve34l will 4move .for bypassing more Vorless of the lexha'ust gases aroundthe' heater casing 22 so as'fto maintain the temperature of ti I and'ope'nsthesupp ythrongh thezppe 2L -By thus by-passing the exhaust gases around the heater caslngi' 22, the latter is permitted e" normal temperature ori pressure is reached. .The ,fuel supply .pipe

lVith this structure, if it is desired-to coolv the engine with water, the valves 18, 48 and '50 are closed andthe valve 16 is opened, whereupon fthe fluid will flow from the source of siipplyl throughthe cooling system. The valve 28 is also closed, and thenipplc 25'is opened.v As the `cylinder member rotates,

to flow through'the iiipple 25 into4 the annu.- lar 'trough 26, from4 which it discharges throughl a 'drain pipe 26 connected with'thefthe centrifugal force will cause the water I' bottom ofthe trough. -If it is desired to use -the li'quid fuel as acooling agent, the valve 16 Vis elosedand the valve 18 is openedand the valves-48 and 50 maylbe lett closed. Said '-fu'el 'will therefore flow vthrough the cooling systenrof .the engine. The nipple 25 ixi'fthis case is-closed while'thevalve 28 is opened. Itwill therefore be evident that inasmuch as the fuel will absorb heat in its passage through the engine, its temperature will bereised' and 'after passing through said engine, it will enter and traverse theeoil 20 n 4by way of the pipe .'27 and from the u per downwardly-bent end of .the latter it wi discharged into 'thecasing 22. 2 Leaving said `casing through t-he'fpipe 30' it -will be vmixed with air at tie carburete-r,` and delivered' to .the engine. I It will be evident ,that in passing through lthe coil and heating casing, it

',will be raised to a high temperature by absorbing the heat fromithe exhaust and will I thus be vaporzed, When the pressure of vapor in theheating casing'reaches a prede-1. terunned degree determined by the spring' 4 6:l the arm 39 ofthe controller will be raised.V Consequentlythrugh the medium of,th"e link44, the'lvalve late 34 will be.

Under certain conditions, it-niay be desired 7 to raise the temperature'of themotive 'fluid ...before it p'aes through the heatingsystem,-

',.inwh-ichcase,the valves' 16 and 18 -are closed andl the valvesf4'8and' y'are opened.v Said.`

mgtiye fluid is then .di urged into the heatgi-caS'Ang rstfvandaffferward will entery the .,jeooling system 'ef-thefengne. With this ar- 13o 990.741', i y: e'

ran rement the vf uel vcan be cut out" of the4 v coolingjsystem entirely by openingthe valve 48'While the YalveslS and50 are closed,

'whereupon the fuel'will be, i'ntroduced into the casing 22' and can flow thencethrough .the pipe'30'to the. engine for the purpose of operating said engine.

From the foregoing,`. it is thought that the construction, operation and many advantages .of the-.herein described invention will b e apparent' to those skilledin the art, without further description, and .it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit .or sacrificing any of the advantages of the invention.
